I introduce `UseGeoSite` and `UseGeoIp` to `depVisitor` to mark this.

I think I should rebase these commits from first commit of this PR right?

I think these commits are a bit messy, so before merging, maybe I need to use "git rebase" to merge all commits into one.

I think this draft is about to be completed so I convert it to a PR. If have any problem, please feel free to call me. ❤️
